Our intro to Daario:
Blue hair, obviously dyed. No one has naturally blue hair
Eyes that are “almost purple” because of the blue hair
Our intro to Young Griff
Blue hair, dyed in the Tyroshi tradition in honor of his dead mother. Or is she??
Tyrion notes that his purple eyes "seem blue" when mixed with the hair.
A perfect parallel.
But why is Daario away from her child and sleeping with a young girl in Slaver’s Bay? Simple. It’s been her agenda this whole time, for she’s been working with Illyrio and Varys. How is she sleeping with Dany? Well, we already know that glamour’s exists in this world. She probably disguised herself as a man to gain Dany’s trust in order to press her son’s claim when Dany moves to Westeros. It’s also possible that Dany is subconsciously aware that Daario is a woman since when he leaves her she turns to Irri for comfort. Coincidence? I think not.
